WATER LEAK DETECTION SYSTEMS "SS" ModelsWHEN WATER FILM FORMS A BRIDGE BETWEENSENSORS (A & A), WATER ALERT BECOMESACTIVATED!PRINCIPLE OF OPERATION ANDCONSTRUCTION "SS" MODELS.5-3/4"*Water Alert is activated by liquid bridging the adjustable sensors (A & A). The unit can detect water filmfrom zero height, (sensors turned out to make contactwith the floor), to 1/8" height, (sensors turned all theway in). The units are factory adjusted to activate with1/32" water film height which is satisfactory for mostapplications. The pads B1 and B2 provide a gap between the case and the surface to admit water underthe unit for detection. If desired, the self adhesive padfeature may be used by peeling off the thin protectivelayer from each pad. The self-adhesive pads along withthe inherent low convex Water Alert profile minimizesthe chance of the unit being inadvertently moved aboutafter being located.

WATER LEAK DETECTION SYSTEMS "VR" ModelsPRINCIPLE OF OPERATION AND CONSTRUCTION "VR" MODELS.The VR Series is activated by water or any conductive fluid bridging the sensors (A & A). Upon activation the externalL.E.D. indicator (B) will light RED. Once the liquid is removed, the VR Water Alert will self re-set. The VR Series is also equipped witha "Wash Down Mode". This feature allows the area to be cleaned with water without activating the Water Alert. The Wash Down Modecan be adjusted from 15 minutes to 2 hours. During this time the sensing circuit in the VR Water Alert is disabled. Once the Wash DownMode times-out, the VR Water Alert will automatically resume sensing liquid. To activate the Wash Down Mode, the cleaning personnel simply pushes the external piezo switch (C). This switch has no moving parts and is touch sensitive. The external L.E.D. (B) will lightGreen, indication the VR Water Alert is now in Wash Down Mode.

CEILING GUARDRWATER LEAKAGE SENSING SYSTEMDorlen Products' Ceiling Guard system is your best defenceto guard against water leakage coming from above yourceiling. Wether its a leaky roof, pipe leaks or above floorflooding, Ceiling Guard will provide early warning of thepotential disaster, aiding in rapid response! INTRODUCTIONThe Dorlen Products’ Ceiling Guard Water Leakage Sensing System is used to sense small amounts of water/liquid leakageabove 2’x4’ or 2’x2’ suspended acoustical ceiling tiles. The system is made up of low profile (1/2” ht.) “troughed” sensing trayswhich contain small sensing contacts. These trays are fastened to the top side of the conventional drop-in ceiling tiles and areinterconnected to form zones of protection.The zones, in turn, are terminated in a Dorlendetector.RThe system is designed to detect and provide indication of smallamounts of leakage before the leakage accumulates to the point ofleaking through, or along the edges of the tiles to the area below.Installing Ceiling Guard provides a very high degree of protectionagainst leakage from concealed piping and the roof or floors abovethe suspended ceiling.Installation is very simple, while individual panel removabilityand overall ceiling appearance is retained. Ceiling Guard can beused with new or existing suspended ceilings. Ceiling Guard isan extension of, and works in conjuction with Dorlen’s Water Alertdetectors.RTop view of 2x4 CeilingGuard Sensing TrayTop view of 2x2 CeilingGuard Sensing Tray17

CEILING GUARDRSERIES 2000 - Ceiling and Ceiling/Floor - Monitored SystemsPRINCIPLE OF OPERATIONEach Ceiling Guard sensing tray contains small sensing contacts. The sensing contacts are parallel connected togetheron the underside of the sensing tray. The ends of the tray have panel-to-panel connectors which are engaged to adjacenttrays during installation. If all trays in an array or zone are dry, a very high electrical resistance exists across the sensingcontacts. Should any tray come in contact with water, the electrical resistance changes abruptly. This resistance changeis detected at the end of the connection by a Dorlen Water Alert Detector. In most cases the Water Alert is Dorlen’s ModelCSS-2000 (See Series 2000 description pgs. 19-24.)The flame retardant plastic sensing trays making up Ceiling Guard are sized to cover either the conventional 2’x4’ or 2’x2’ceiling tiles. The smallest amount of water leakage into any sensing tray quickly finds its way to a sensing contact locatedin the trough of the tray thereby activating the associated detector.Galvanized barbedfasteners or staples(provided) fasten trays toNon-Gender Panel-to Panel connector (anyEnd ribs stiffenconnector engages any other)panel and retain- Latched engage/releaseliquid leakage-Gold plated contactsceiling tilesTo CGM Series2000 MonitorCSS-2000 Water Alert Detector.Each Zone (up to 5 tray packs,320 sq.ft.) will terminate in adetector which provides audibleNon-corrosive, gold plated sensingalarms for water sensed or sens-contacts covered by dust coversing tray cable break, and signalsCeiling Guard Monitor (CGM)alarm panel.TYPICAL ABOVE CEILING VIEW18
